The present invention relates to a WLAN AP service providing system using a portable Internet terminal. More specifically, a portable Internet terminal that uses a portable Internet terminal as an AP to connect a laptop and a PDA having a wireless LAN function to the portable Internet system, or provides a hub function to perform wireless communication between the laptop and the PDA. It relates to a wireless LAN AP service providing system using.

With the rapid development of computer, electronic and communication technologies, various wireless communication services using a wireless communication network have been provided. The most basic wireless communication service is a wireless voice call service that provides a voice call to a mobile terminal user wirelessly, which can provide a service regardless of time and place. In addition, while supplementing a voice call service by providing a text message, a wireless Internet service has recently emerged to provide an Internet service to a user of a mobile communication terminal through a wireless communication network.

As a result of the development of communication technology, a service provided by a code division multiple access (CDMA) system is not only a voice service but also a multimedia communication service that transmits data such as circuit data and packet data. Is developing.

The mobile communication system has been developed through the first generation analog AMPS (Advanced Mobile Phone System) method and the second generation cellular (Cellular) / Personal Communication Service (PCS) method. The third generation mobile communication system IMT-2000 (International Mobile Telecommunication 2000), which is enacted as a standard in ITU-R, is commercially available. IMT-2000 is CDMA 2000 1X, 3X, EV-DO, Wideband CDMA (WCDMA), etc., and is used in IS-95A and IS-95B networks by using the IS-95C network that has evolved from the existing IS-95A and IS-95B networks. It is a service that can provide wireless Internet at a transmission speed of up to 144 Kbps, much faster than the supportable data transmission speed of 14.4 Kbps or 56 Kbps. In particular, by using IMT-2000 service, it is possible to provide various multimedia services (AOD, VOD, etc.) at a faster speed as well as improving existing voice and wireless broadcasting service (WBS) service quality.

However, the existing mobile communication system has a limitation in providing high-speed wireless Internet due to high base station construction cost and high usage fee of the wireless Internet, and a small screen size of the mobile communication terminal. (Wireless Local Area Network) technology has limitations in providing public services due to problems such as radio wave interference and narrow coverage. Accordingly, a mobile Internet system (Wibro: Wireless Broadband Internet or PI: Portable Internet), which can use a high-speed wireless Internet service at a low cost while moving, has emerged.

The portable internet system uses various types of portable terminals such as laptops, PDAs, and handheld PCs to access various types of information and content by accessing the Internet in indoor and outdoor stationary environments and in mobile environments with walking speeds and low to medium speeds. It is a service. In addition, it provides mobility of 60 km / h per hour, provides downlink transmission speed of 24 Mbps, and can provide downlink transmission speed of 50 Mbps by applying Multiple Input Multiple Output (MIMO) system. Wireless data system.

In addition, the portable Internet system uses a 2.3 GHz frequency band, and time division duplex (TDD) and multiple access (DDD) methods are used as duplex methods to effectively use the allocated frequency spectrum. Orthogonal Frequency Division Multiple Access (OFDMA) is used.

Conventional mobile communication terminals using such wireless communication services have been used, including terminals such as a handset type, a personal computer memory card international association (PCMCIA) type, and a personal digital assistant (PDA) type. In order to utilize high-speed data transmission of a portable Internet system by using a single mobile communication terminal, a mobile communication terminal in the form of a customer premises equipment (CPE) has emerged.

The handset type is a type of mobile communication terminal which is most used at present. It mainly processes data using the processor of the terminal itself. The PCMCIA type is connected to a device in which the mobile communication terminal is not connected to a mobile communication service such as a laptop. It replaces the role of modem. The PDA type is a PCMCIA type with PDA. At the same time, most of them have a wireless LAN function. In the case of notebooks that mainly use the PCMCIA type, most of them support the WLAN function. have.

Most CPE-type mobile communication terminals in the portable Internet system are configured to receive wireless portable Internet resources and connect to other devices by wire, and are mainly connected in the form of wired LAN to perform communication between devices. Doing.

As described above, the conventional mobile communication terminal mainly uses two methods of using the radio resources of the mobile Internet system independently by the mobile communication terminal or by converting the wireless resource into a wired LAN using the CPE type mobile communication terminal. There was no equipment that directly converts the system's radio resources into the form of WLAN.

In order to solve the above problems, the present invention, using a portable Internet terminal as an AP to connect a laptop and PDA having a wireless LAN function to the portable Internet system, or to perform a wireless communication between the laptop (Hub) and the PDA (Hub) An object of the present invention is to provide a WLAN AP service providing system using a portable Internet terminal providing a function.
